By arranging the sliding seat 8, the mutual abrasion between the driving traction rope 6 and the driving mechanism does not exist, and the abrasion between the fixed pulley and the driving traction rope 6 is small, so that the maintenance period of the driving traction rope 6 in the invention is shorter. In addition, the pumping unit uses a period of time after, the length of drive haulage rope 6 can increase, this moment, only need in the junction of drive haulage rope 6 and slide 8 to drive the haulage rope 6 the length adjust can, through convenient adjustment means, eliminated the drive haulage rope 6 extension to the adverse effect of pumping unit operation.

After the motor 12 is started, the rotating disc 14 rotates under the driving of the motor 12, the rotating disc 14 enables the rocker arm to swing through the matching of the short shaft 21 and the slide way 10, the swinging rocker arm drives the sliding seat 8 to move horizontally through the gear rack transmission mechanism, and finally the walking beam 3 is driven through driving the traction rope 6.
And the transmission mechanism in the driving device is a winding drum transmission mechanism.
As shown in fig. 3, the motor 12 is a dual-shaft motor having output shafts at both ends, the drum transmission mechanism includes four drums 13, two drums 13 are mounted on two output shafts of the motor 12 and driven by the motor 12 to rotate, the other two drums 13 are fixedly mounted at both ends of a central shaft of the turntable 14, and the motor 12 and the two drums 13 on the same side of the turntable 14 are connected by a winding rope 20. The invention adopts a reel transmission mechanism to realize the power connection between the motor 12 and the turntable 14, when the oil pumping unit works, the motor 12 switches the steering once after the oil pumping unit works for a plurality of strokes, and the two winding ropes 20 work alternately. When the motor 12 rotates forwards, one end of a winding rope 20 is wound by the winding drum 13 connected to the motor 12, and meanwhile, the other end of the winding rope 20 winds down from the winding drum 13 connected to the rotating disc 14; one end of another winding rope 20 is wound off from the winding drum 13 connected to the motor 12, and at the same time, the other end of the winding rope 20 is wound on the winding drum 13 connected to the turntable 14.

To solve this problem, a roll 13 having a structure as shown in fig. 4 may be manufactured. In fig. 4, an insertion portion 22 is fixed to an output shaft 23 of the motor 12, the insertion portion 22 is inserted into the winding drum 13 and can slide axially relative to the winding drum, a screw hole is formed in the center of the winding drum 13, a stud 24 is connected to the screw hole through a trapezoidal thread, the stud 24 is fixed relative to the base 7 or the bracket 4 of the pumping unit, and the pitch of the stud 24 is the same as the pitch of a spiral line wound by the winding rope 20 and the rotating direction is the same. The reels 13 on the wheel discs 14 can likewise be designed in this way. Thus, when the output shaft 23 of the motor 12 rotates, the winding drum 23 can move axially under the action of the stud 24, so that the winding rope 20 and the ground are kept relatively still all the time, and the effect of reducing the abrasion is achieved.
